As used herein, the term “composition” refers to a formulation suitablefor administration to an intended animal subject for therapeuticpurposes that contains at least one pharmaceutically active compound andat least one pharmaceutically acceptable carrier or excipient.

The term “pharmaceutically acceptable” indicates that the indicatedmaterial does not have properties that would cause a reasonably prudentmedical practitioner to avoid administration of the material to apatient, taking into consideration the disease or conditions to betreated and the respective route of administration. For example, it iscommonly required that such a material be essentially sterile, e.g., forinjectibles.

In the present context, the term “therapeutically effective” or“effective amount” indicates that the materials or amount of material iseffective to prevent, alleviate, or ameliorate one or more symptoms of adisease or medical condition, and/or to prolong the survival of thesubject being treated.

In the present context, the terms “synergistically effective” or“synergistic effect” indicate that two or more compounds that aretherapeutically effective, when used in combination, provide improvedtherapeutic effects greater than the additive effect that would beexpected based on the effect of each compound used by itself.

As used herein, the terms “ligand” and “modulator” are used equivalentlyto refer to a compound that changes (i.e., increases or decreases) theactivity of a target biomolecule, e.g., an enzyme such as a kinase. Theterm “inhibitor” refers to a modulator that decreases the activity ofthe target biomolecule. Generally a ligand or modulator will be a smallmolecule, where “small molecule refers to a compound with a molecularweight of 1500 daltons or less, or preferably 1000 daltons or less, 800daltons or less, or 600 daltons or less.

In the context of compounds binding to a target, the terms “greateraffinity” and “selective” indicates that the compound binds more tightlythan a reference compound, or than the same compound in a referencecondition, i.e., with a lower dissociation constant. In someembodiments, the greater affinity (i.e. selectivity) is at least 2, 3,4, 5, 8, 10, 50, 100, 200, 400, 500, 1000, or 10,000-fold greateraffinity.

As used herein in connection with compounds of the invention, the term“synthesizing” and like terms means chemical synthesis from one or moreprecursor materials.

By “assaying” is meant the creation of experimental conditions and thegathering of data regarding a particular result of the experimentalconditions. For example, enzymes can be assayed based on their abilityto act upon a detectable substrate. A compound or ligand can be assayedbased on its ability to bind to a particular target molecule ormolecules.

As used herein, the term “modulating” or “modulate” refers to an effectof altering a biological activity, especially a biological activityassociated with a particular biomolecule such as a protein kinase. Forexample, an agonist or antagonist of a particular biomolecule modulatesthe activity of that biomolecule, e.g., an enzyme, by either increasing(e.g. agonist, activator), or decreasing (e.g. antagonist, inhibitor)the activity of the biomolecule, such as an enzyme. Such activity istypically indicated in terms of an inhibitory concentration (IC₅₀) orexcitation concentration (EC₅₀) of the compound for an inhibitor oractivator, respectively, with respect to, for example, an enzyme.

In the context of the use, testing, or screening of compounds that areor may be modulators, the term “contacting” means that the compound(s)are caused to be in sufficient proximity to a particular molecule,complex, cell, tissue, organism, or other specified material thatpotential binding interactions and/or chemical reaction between thecompound and other specified material can occur.

As used herein in connection with amino acid or nucleic acid sequence,the term “isolate” indicates that the sequence is separated from atleast a portion of the amino acid and/or nucleic acid sequences withwhich it would normally be associated.

In connection with amino acid or nucleic sequences, the term “purified”indicates that the subject molecule constitutes a significantly greaterproportion of the biomolecules in a composition than the proportionobserved in a prior composition, e.g., in a cell culture. The greaterproportion can be 2-fold, 5-fold, 10-fold, or more than 10-fold, withrespect to the proportion found in the prior composition.

A-Raf:

Target kinase A-Raf (i.e., v-raf murine sarcoma 3611 viral oncogenehomolog 1) is a 67.6 kDa serine/threonine kinase encoded by chromosomeXp11.4-p11.2 (symbol: ARAF). The mature protein comprises RBD (i.e., Rasbinding domain) and phorbol-ester/DAG-type zinc finger domain and isinvolved in the transduction of mitogenic signals from the cell membraneto the nucleus. A-Raf inhibitors may be useful in treating neurologicdiseases such as multi-infarct dementia, head injury, spinal cordinjury, Alzheimer's disease (AD), Parkinson's disease; neoplasticdiseases including, but not limited to, melanoma, glioma, sarcoma,carcinoma (e.g. colorectal, lung, breast, pancreatic, thyroid, renal,ovarian), lymphoma (e.g. histiocytic lymphoma), neurofibromatosis,myelodysplastic syndrome, leukemia, tumor angiogenesis; pain ofneuropathic or inflammatory origin, including acute pain, chronic pain,cancer-related pain and migraine; and diseases associated with muscleregeneration or degeneration, including, but not limited to, vascularrestenosis, sarcopenia, muscular dystrophies (including, but not limitedto, Duchenne, Becker, Emery-Dreifuss, Limb-Girdle, Facioscapulohumeral,Myotonic, Oculopharyngeal, Distal and Congenital Muscular Dystrophies),motor neuron diseases (including, but not limited to, amyotrophiclateral sclerosis, infantile progressive spinal muscular atrophy,intermediate spinal muscular atrophy, juvenile spinal muscular atrophy,spinal bulbar muscular atrophy, and adult spinal muscular atrophy),inflammatory myopathies (including, but not limited to, dermatomyositis,polymyositis, and inclusion body myositis), diseases of theneuromuscular junction (including, but not limited to, myastheniagravis, Lambert-Eaton syndrome, and congenital myasthenic syndrome),myopathies due to endocrine abnormalities (including, but not limitedto, hyperthyroid myopathy and hypothyroid myopathy) diseases ofperipheral nerve (including, but not limited to, Charcot-Marie-Toothdisease, Dejerine-Sottas disease, and Friedreich's ataxia), othermyopathies (including, but not limited to, myotonia congenita,paramyotonia congenita, central core disease, nemaline myopathy,myotubular myopathy, and periodic paralysis), and metabolic diseases ofmuscle (including, but not limited to, phosphorylase deficiency, acidmaltase deficiency, phosphofructokinase deficiency, debrancher enzymedeficiency, mitochondrial myopathy, carnitine deficiency, carnitinepalmatyl transferase deficiency, phosphoglycerate kinase deficiency,phosphoglycerate mutase deficiency, lactate dehydrogenase deficiency,and myoadenylate deaminase deficiency).

B-Raf:

Target kinase B-Raf (i.e., v-raf murine sarcoma viral oncogene homologB1) is a 84.4 kDa serine/threonine kinase encoded by chromosome 7q34(symbol: BRAF). The mature protein comprises RBD (i.e., Ras bindingdomain), Cl (i.e., protein kinase C conserved region 1) and STK (i.e.,serine/threonine kinase) domains.

Target kinase B-Raf is involved in the transduction of mitogenic signalsfrom the cell membrane to the nucleus and may play a role in thepostsynaptic responses of hippocampal neurons. As such, genes of the RAFfamily encode kinases that are regulated by Ras and mediate cellularresponses to growth signals. Indeed, B-Raf kinase is a key component ofthe RAS->Raf->MEK->ERK/MAP kinase signaling pathway, which plays afundamental role in the regulation of cell growth, division andproliferation, and, when constitutively activated, causes tumorigenesis.Among several isoforms of Raf kinase, the B-type, or B-Raf, is thestrongest activator of the downstream MAP kinase signaling.

The BRAF gene is frequently mutated in a variety of human tumors,especially in malignant melanoma and colon carcinoma. The most commonreported mutation was a missense thymine (T) to adenine (A) transversionat nucleotide 1796 (T1796A; amino acid change in the B-Raf protein isVal<600> to Glu<600>) observed in 80% of malignant melanoma tumors.Functional analysis reveals that this transversion is the only detectedmutation that causes constitutive activation of B-Raf kinase activity,independent of RAS activation, by converting B-Raf into a dominanttransforming protein. Based on precedents, human tumors developresistance to kinase inhibitors by mutating a specific amino acid in thecatalytic domain as the “gatekeeper”. (Balak, et. al., Clin Cancer Res.2006, 12:6494-501). Mutation of Thr-529 in BRAF to Ile is thusanticipated as a mechanism of resistance to BRAF inhibitors, and thiscan be envisioned as a transition in codon 529 from ACC to ATC.

Niihori et al., report that in 43 individuals withcardio-facio-cutaneous (CFC) syndrome, they identified two heterozygousKRAS mutations in three individuals and eight BRAF mutations in 16individuals, suggesting that dysregulation of the RAS-RAF-ERK pathway isa common molecular basis for the three related disorders (Niihori etal., Nat. Genet. 2006, 38(3):294-6).

c-Raf-1:

Target kinase c-Raf-1 (i.e., v-raf murine sarcoma viral oncogenehomolog 1) is a 73.0 kDa STK encoded by chromosome 3p25 (symbol: RAFT).c-Raf-1 can be targeted to to the mitochondria by BCL2 (i.e., oncogeneB-cell leukemia 2) which is a regulator of apoptotic cell death. Activec-Raf-1 improves BCL2-mediated resistance to apoptosis, and c-Raf-1phosphorylates BAD (i.e., BCL2-binding protein). c-Raf-1 is implicatedin carcinomas, including colorectal, ovarian, lung and renal cellcarcinoma. C-Raf-1 is also implicated as an important mediator of tumorangiogenesis (Hood, J. D. et al., 2002, Science 296, 2404). C-Raf-1inhibitors may also be useful for the treatment of acute myeloidleukemia and myelodysplastic syndromes (Crump, Curr Pharm Des 2002,8(25):2243-8). Raf-1 activators may be useful as treatment forneuroendocrine tumors, such as medullary thyroid cancer, carcinoid,small cell lung cancer and pheochromocytoma (Kunnimalaiyaan et al.,Anticancer Drugs 2006, 17(2):139-42).

Raf inhibitors (A-Raf and/or B-Raf and/or c-Raf-1) may be useful intreating A-Raf-mediated, B-Raf-mediated or c-Raf-1-mediated disease orcondition selected from the group consisting of neurologic diseases,including, but not limited to, multi-infarct dementia, head injury,spinal cord injury, Alzheimer's disease (AD), Parkinson's disease;neoplastic diseases including, but not limited to, melanoma, glioma,sarcoma, carcinoma (e.g. colorectal, lung, breast, pancreatic, thyroid,renal, ovarian), lymphoma (e.g. histiocytic lymphoma) neurofibromatosis,acute myeloid leukemia, myelodysplastic syndrome, leukemia, tumorangiogenesis, neuroendocrine tumors such as medullary thyroid cancer,carcinoid, small cell lung cancer and pheochromocytoma; pain ofneuropathic or inflammatory origin, including, but not limited to, acutepain, chronic pain, cancer-related pain, and migraine; cardiovasculardiseases, including, but not limited to, heart failure, ischemic stroke,cardiac hypertrophy, thrombosis (e.g. thrombotic microangiopathysyndromes), atherosclerosis, and reperfusion injury; inflammationincluding, but not limited to, psoriasis, arthritis and autoimmunediseases and conditions, osteoarthritis, endometriosis, scarring,vascular restenosis, fibrotic disorders, rheumatoid arthritis,inflammatory bowel disease (IBD); immunodeficiency diseases, including,but not limited to, organ transplant rejection, graft versus hostdisease; renal or prostatic diseases, including, but not limited to,diabetic nephropathy, polycystic kidney disease, nephrosclerosis,glomerulonephritis, prostate hyperplasia; metabolic disorders,including, but not limited to, obesity; infection, including, but notlimited to, Helicobacter pylori, Hepatitis and Influenza viruses, fever,and sepsis; pulmonary diseases, including, but not limited to, chronicobstructive pulmonary disease (COPD) and acute respiratory distresssyndrome (ARDS); genetic developmental diseases, including, but notlimited to, Noonan's syndrome, Costello syndrome, (faciocutaneoskeletalsyndrome), LEOPARD syndrome, cardio-faciocutaneous syndrome (CFC), andneural crest syndrome abnormalities causing cardiovascular, skeletal,intestinal, skin, hair and endocrine diseases.

Kinase Activity Assays

A number of different assays for kinase activity can be utilized forassaying for active modulators and/or determining specificity of amodulator for a particular kinase or group or kinases. In addition tothe assay mentioned in the Examples below, one of ordinary skill in theart will know of other assays that can be utilized and can modify anassay for a particular application. For example, numerous papersconcerning kinases describe assays that can be used.

Additional alternative assays can employ binding determinations. Forexample, this sort of assay can be formatted either in a fluorescenceresonance energy transfer (FRET) format, or using an AlphaScreen(amplified luminescent proximity homogeneous assay) format by varyingthe donor and acceptor reagents that are attached to streptavidin or thephosphor-specific antibody.

Organic Synthetic Techniques

A wide array of organic synthetic techniques exist in the art tofacilitate the construction of potential modulators. Many of theseorganic synthetic methods are described in detail in standard referencesources utilized by those skilled in the art. One example of such areference is March, 1994, Advanced Organic Chemistry; Reactions,Mechanisms and Structure, New York, McGraw Hill. Thus, the techniquesuseful to synthesize a potential modulator of kinase function arereadily available to those skilled in the art of organic chemicalsynthesis.

Alternative Compound Forms or Derivatives

Compounds contemplated herein are described with reference to bothgeneric formulae and specific compounds. In addition, inventioncompounds may exist in a number of different forms or derivatives, allwithin the scope of the present invention. Alternative forms orderivatives, include, for example, (a) prodrugs, and active metabolites(b) tautomers, isomers (including stereoisomers and regioisomers), andracemic mixtures (c) pharmaceutically acceptable salts and formulationsand (d) solid forms, including different crystal forms, polymorphic oramorphous solids, including hydrates and solvates thereof, and otherforms.

(a) Prodrugs and Metabolites

In addition to the present formulae and compounds described herein, theinvention also includes prodrugs (generally pharmaceutically acceptableprodrugs), active metabolic derivatives (active metabolites), and theirpharmaceutically acceptable salts.

Prodrugs are compounds or pharmaceutically acceptable salts thereofwhich, when metabolized under physiological conditions or when convertedby solvolysis, yield the desired active compound. Prodrugs include,without limitation, esters, amides, carbamates, carbonates, ureides,solvates, or hydrates of the active compound. Typically, the prodrug isinactive, or less active than the active compound, but may provide oneor more advantageous handling, administration, and/or metabolicproperties. For example, some prodrugs are esters of the activecompound; during metabolysis, the ester group is cleaved to yield theactive drug. Esters include, for example, esters of a carboxylic acidgroup, or S-acyl or O-acyl derivatives of thiol, alcohol, or phenolgroups. In this context, a common example is an alkyl ester of acarboxylic acid. Some prodrugs are activated enzymatically to yield theactive compound, or a compound which, upon further chemical reaction,yields the active compound. Prodrugs may proceed from prodrug form toactive form in a single step or may have one or more intermediate formswhich may themselves have activity or may be inactive.

As described in The Practice of Medicinal Chemistry, Ch. 31-32 (Ed.Wermuth, Academic Press, San Diego, Calif., 2001), prodrugs can beconceptually divided into two non-exclusive categories, bioprecursorprodrugs and carrier prodrugs. Generally, bioprecursor prodrugs arecompounds that are inactive or have low activity compared to thecorresponding active drug compound, that contain one or more protectivegroups and are converted to an active form by metabolism or solvolysis.Both the active drug form and any released metabolic products shouldhave acceptably low toxicity. Typically, the formation of active drugcompound involves a metabolic process or reaction that is one of thefollow types:

Oxidative reactions: Oxidative reactions are exemplified withoutlimitation to reactions such as oxidation of alcohol, carbonyl, and acidfunctionalities, hydroxylation of aliphatic carbons, hydroxylation ofalicyclic carbon atoms, oxidation of aromatic carbon atoms, oxidation ofcarbon-carbon double bonds, oxidation of nitrogen-containing functionalgroups, oxidation of silicon, phosphorus, arsenic, and sulfur, oxidativeN-dealkylation, oxidative O- and S-dealkylation, oxidative deamination,as well as other oxidative reactions.

Reductive reactions: Reductive reactions are exemplified withoutlimitation to reactions such as reduction of carbonyl functionalitites,reduction of alcohol functionalities and carbon-carbon double bonds,reduction of nitrogen-containing functional groups, and other reductionreactions.

Reactions without change in the oxidation state: Reactions withoutchange in the state of oxidation are exemplified without limitation toreactions such as hydrolysis of esters and ethers, hydrolytic cleavageof carbon-nitrogen single bonds, hydrolytic cleavage of non-aromaticheterocycles, hydration and dehydration at multiple bonds, new atomiclinkages resulting from dehydration reactions, hydrolyticdehalogenation, removal of hydrogen halide molecule, and other suchreactions.

Carrier prodrugs are drug compounds that contain a transport moiety,e.g., that improves uptake and/or localized delivery to a site(s) ofaction. Desirably for such a carrier prodrug, the linkage between thedrug moiety and the transport moiety is a covalent bond, the prodrug isinactive or less active than the drug compound, the prodrug and anyrelease transport moiety are acceptably non-toxic. For prodrugs wherethe transport moiety is intended to enhance uptake, typically therelease of the transport moiety should be rapid. In other cases, it isdesirable to utilize a moiety that provides slow release, e.g., certainpolymers or other moieties, such as cyclodextrins. (See, e.g., Cheng etal., U.S. Patent Publ. No. 20040077595, application Ser. No. 10/656,838,incorporated herein by reference.) Such carrier prodrugs are oftenadvantageous for orally administered drugs. In some instances, thetransport moiety provides targeted delivery of the drug, for example thedrug maybe conjugated to an antibody or antibody fragment. Carrierprodrugs can, for example, be used to improve one or more of thefollowing properties: increased lipophilicity, increased duration ofpharmacological effects, increased site-specificity, decreased toxicityand adverse reactions, and/or improvement in drug formulation (e.g.,stability, water solubility, suppression of an undesirable organolepticor physiochemical property). For example, lipophilicity can be increasedby esterification of hydroxyl groups with lipophilic carboxylic acids,or of carboxylic acid groups with alcohols, e.g., aliphatic alcohols.Wermuth, supra.

Metabolites, e.g., active metabolites, overlap with prodrugs asdescribed above, e.g., bioprecursor prodrugs. Thus, such metabolites arepharmacologically active compounds or compounds that further metabolizeto pharmacologically active compounds that are derivatives resultingfrom metabolic processes in the body of a subject. Of these, activemetabolites are such pharmacologically active derivative compounds. Forprodrugs, the prodrug compound is generally inactive or of loweractivity than the metabolic product. For active metabolites, the parentcompound may be either an active compound or may be an inactive prodrug.For example, in some compounds, one or more alkoxy groups can bemetabolized to hydroxyl groups while retaining pharmacologic activityand/or carboxyl groups can be esterified, e.g., glucuronidation. In somecases, there can be more than one metabolite, where an intermediatemetabolite(s) is further metabolized to provide an active metabolite.For example, in some cases a derivative compound resulting frommetabolic glucuronidation may be inactive or of low activity, and can befurther metabolized to provide an active metabolite.

Metabolites of a compound may be identified using routine techniquesknown in the art, and their activities determined using tests such asthose described herein. See, e.g., Bertolini et al., 1997, J. Med.Chem., 40:2011-2016; Shan et al., 1997, J Pharm Sci 86(7):756-757;Bagshawe, 1995, Drug Dev. Res., 34:220-230; Wermuth, supra.

(b) Tautomers, Stereoisomers, and Regioisomers

It is understood that some compounds may exhibit tautomerism. In suchcases, the formulae provided herein expressly depict only one of thepossible tautomeric forms. It is therefore to be understood that theformulae provided herein are intended to represent any tautomeric formof the depicted compounds and are not to be limited merely to thespecific tautomeric form depicted by the drawings of the formulae.

Likewise, some of the compounds according to the present invention mayexist as stereoisomers, i.e. having the same atomic connectivity ofcovalently bonded atoms yet differing in the spatial orientation of theatoms. For example, compounds may be optical stereoisomers, whichcontain one or more chiral centers, and therefore, may exist in two ormore stereoisomeric forms (e.g. enantiomers or diastereomers). Thus,such compounds may be present as single stereoisomers (i.e., essentiallyfree of other stereoisomers), racemates, and/or mixtures of enantiomersand/or diastereomers. As another example, stereoisomers includegeometric isomers, such as cis- or trans-orientation of substituents onadjacent carbons of a double bond. All such single stereoisomers,racemates and mixtures thereof are intended to be within the scope ofthe present invention. Unless specified to the contrary, all suchsteroisomeric forms are included within the formulae provided herein.

In some embodiments, a chiral compound of the present invention is in aform that contains at least 80% of a single isomer (60% enantiomericexcess (“e.e.”) or diastereomeric excess (“d.e.”)), or at least 85% (70%e.e. or d.e.), 90% (80% e.e. or d.e.), 95% (90% e.e. or d.e.), 97.5%(95% e.e. or d.e.), or 99% (98% e.e. or d.e.). As generally understoodby those skilled in the art, an optically pure compound having onechiral center is one that consists essentially of one of the twopossible enantiomers (i.e., is enantiomerically pure), and an opticallypure compound having more than one chiral center is one that is bothdiastereomerically pure and enantiomerically pure. In some embodiments,the compound is present in optically pure form, such optically pure formbeing prepared and/or isolated by methods known in the art (e.g. byrecrystallization techniques, chiral synthetic techniques (includingsynthesis from optically pure starting materials), and chromatographicseparation using a chiral column.

(c) Pharmaceutically Acceptable Salts and Formulations

Unless specified to the contrary, specification of a compound hereinincludes pharmaceutically acceptable salts of such compound. Thus,compounds of Formula I can be in the form of pharmaceutically acceptablesalts, or can be formulated as pharmaceutically acceptable salts.Contemplated pharmaceutically acceptable salt forms include, withoutlimitation, mono, bis, tris, tetrakis, and so on. Pharmaceuticallyacceptable salts are non-toxic in the amounts and concentrations atwhich they are administered. The preparation of such salts canfacilitate the pharmacological use by altering the physicalcharacteristics of a compound without preventing it from exerting itsphysiological effect. Useful alterations in physical properties includelowering the melting point to facilitate transmucosal administration andincreasing the solubility to facilitate administering higherconcentrations of the drug. A compound of the invention may possess asufficiently acidic, a sufficiently basic, or both functional groups,and accordingly react with any of a number of inorganic or organicbases, and inorganic and organic acids, to form a pharmaceuticallyacceptable salt.

Pharmaceutically acceptable salts include acid addition salts such asthose containing chloride, bromide, iodide, hydrochloride, acetate,phenylacetate, acrylate, ascorbate, aspartate, benzoate,2-phenoxybenzoate, 2-acetoxybenzoate, dinitrobenzoate, hydroxybenzoate,methoxybenzoate, methylbenzoate, bicarbonate, butyne-1,4 dioate,hexyne-1,6-dioate, caproate, caprylate, chlorobenzoate, cinnamate,citrate, decanoate, formate, fumarate, glycolate, gluconate, glucarate,glucuronate, glucose-6-phosphate, glutamate, heptanoate, hexanoate,isethionate, isobutyrate, gamma-hydroxybutyrate, phenylbutyrate,lactate, malate, maleate, hydroxymaleate, methylmaleate, malonate,mandelate, nicotinate, nitrate, isonicotinate, octanoate, oleate,oxalate, pamoate, phosphate, monohydrogenphosphate, dihydrogenphosphate,orthophosphate, metaphosphate, pyrophosphate, 2-phosphoglycerate,3-phosphoglycerate, phthalate, propionate, phenylpropionate, propiolate,pyruvate, quinate, salicylate, 4-aminosalicylate, sebacate, stearate,suberate, succinate, sulfate, pyrosulfate, bisulfate, sulfite,bisulfite, sulfamate, sulfonate, benzenesulfonate (i.e. besylate),ethanesulfonate (i.e. esylate), ethane-1,2-disulfonate,2-hydroxyethanesulfonate (i.e. isethionate), methanesulfonate (i.e.mesylate), naphthalene-1-sulfonate, naphthalene-2-sulfonate (i.e.napsylate), propanesulfonate, p-toluenesulfonate (i.e. tosylate),xylenesulfonates, cyclohexylsulfamate, tartrate, and trifluoroacetate.These pharmaceutically acceptable acid addition salts can be preparedusing the appropriate corresponding acid.

When acidic functional groups, such as carboxylic acid or phenol arepresent, pharmaceutically acceptable salts also include basic additionsalts such as those containing benzathine, chloroprocaine, choline,ethanolamine, diethanolamine, triethanolamine, t-butylamine,dicyclohexylamine, ethylenediamine, N,N′-dibenzylethylenediamine,meglumine, hydroxyethylpyrrolidine, piperidine, morpholine, piperazine,procaine, aluminum, calcium, copper, iron, lithium, magnesium,manganese, potassium, sodium, zinc, ammonium, and mono-, di-, ortri-alkylamines, or salts derived from amino acids such as L-histidine,L-glycine, L-lysine, and L-arginine. For example, see Remington'sPharmaceutical Sciences, 19^(th) ed., Mack Publishing Co., Easton, Pa.,Vol. 2, p. 1457, 1995. These pharmaceutically acceptable base additionsalts can be prepared using the appropriate corresponding base.

Pharmaceutically acceptable salts can be prepared by standardtechniques. For example, the free-base form of a compound can bedissolved in a suitable solvent, such as an aqueous or aqueous-alcoholsolution containing the appropriate acid and then isolated byevaporating the solution. In another example, a salt can be prepared byreacting the free base and acid in an organic solvent. If the particularcompound is an acid, the desired pharmaceutically acceptable salt may beprepared by any suitable method, for example, treatment of the free acidwith an appropriate inorganic or organic base.

The pharmaceutically acceptable salt of the different compounds may bepresent as a complex. Examples of complexes include 8-chlorotheophyllinecomplex (analogous to, e.g., dimenhydrinate: diphenhydramine8-chlorotheophylline (1:1) complex; Dramamine) and various cyclodextrininclusion complexes.

(d) Other Compound Forms

In the case of agents that are solids, it is understood by those skilledin the art that the compounds and salts may exist in different crystalor polymorphic forms, or may be formulated as co-crystals, or may be inan amorphous form, or may be any combination thereof (e.g. partiallycrystalline, partially amorphous, or mixtures of polymorphs) all ofwhich are intended to be within the scope of the present invention andspecified formulae. Whereas salts are formed by acid/base addition, i.e.a free base or free acid of the compound of interest forms an acid/basereaction with a corresponding addition base or addition acid,respectively, resulting in an ionic charge interaction, co-crystals area new chemical species that is formed between neutral compounds,resulting in the compound and an additional molecular species in thesame crystal structure.

Additionally, the formulae are intended to cover hydrated or solvated aswell as unhydrated or unsolvated forms of the identified structures. Forexample, the indicated structures include both hydrated and non-hydratedforms. Other examples of solvates include the structures in combinationwith a suitable solvent, such as isopropanol, ethanol, methanol,dimethylsulfoxide, ethyl acetate, acetic acid, or ethanolamine.

To be administered in the form of atransdermal delivery system, the dosage administration will becontinuous rather than intermittent throughout the dosage regimen.

In some embodiments, compounds are administered as inhalants. Compoundsof Formula I may be formulated as dry powder or a suitable solution,suspension, or aerosol. Powders and solutions may be formulated withsuitable additives known in the art. For example, powders may include asuitable powder base such as lactose or starch, and solutions maycomprise propylene glycol, sterile water, ethanol, sodium chloride andother additives, such as acid, alkali and buffer salts. Such solutionsor suspensions may be administered by inhaling via spray, pump,atomizer, or nebulizer, and the like.
